These items were used outdoors. The gray one is an ant deterrent; you fill the surrounding area with water. The white one, when a plastic bottle is attached, stays full of water. I used them for about a year. There are scratches and stains from use that won't come off even after washing. I have bleached and cleaned them. I have inspected them as carefully as possible, but there may be oversights. Please be aware of this. These are used items stored by a private individual. Please purchase them only if you are satisfied with their condition. Please purchase only if you are willing to accept shipping with no cushioning material, only protection against water damage.
